at, extending rearwardly therefrom. Our invention broadly consists of the de- B is a shallow open box consisting of aback vices as thus described 5 but they are susceptible of certain modifications, which may be employed in connection therewith without departing from the leading scope and purview of said invention, as follows: The orifices b in the panel I) may be dispensed with, if desired, in which case the locking-plate must be curved or arched, (see Fig. 6,) thereby leaving a space between the lower surface of said plate and the upper surface of the panel Z) of sufficient depth to admit therein the notched pins a of the mounting A.

In the drawings we illustrate a small spring, 8, which may, if desired, be attached either to the end of the plate or within the box, the function of which spring will be to maintain the plate O always pressed upwardly within the box, but which spring will readily yield when said plate is moved in a contrary direction.

From the foregoing description, in connection with the drawings, the nature and object and the operation of our invention will be readily understood by all persons familiar with the line of art to which ourimprovement is allied.

Its operation may be briefly explained as follows: The incasement or box B, being without any mounting, has the plate 0 pushed downwardly into the position illustrated in Fig. 2. This is eifected by pressing a wire or ordinary pin upon the upper exposed end of the pin 0, which is seated within the orifice b at the upper end of the box-frame. (See indieating arrows.) The result will be that the lower end of the pin 0 will be ejected through the aperture 73 upon the lower end of the boxframe, while at the same time the upper end of the pin 0 will pass downwardly within the short tube b It will be manifest that the opposite edge of the plate C, being confined within the annular groove 2, will slide therein, and there will be no risk of displacing said plate laterally or otherwise. The circular member of each key-hole slot will be thus brought into juxtaposition with the underlying orifices b of the panel I), and the respective openings will coincide. The mounting is now inserted in place, the pins a thereof taking within the respective united openings of the sliding plate and panel, which have been brought into alignment, as before set forth. Pressure is now applied (in direction of arrow w)-to the lower end of the pin 0, which is projecting downwardly through the under edge of the frame. The effect will be that the plal e C is pushed upwardly into the position shown in Fig. 3, and the device is securely locked in place.

The same operation is followed when an arched plate, as shown in Fig. 6, is employed, and wherein the orifices upon the panel I) are dispensed with, for .it will be readily understood that in that case the narrowed portion of the key-hole slots, will securely grasp the notched pins a when caused to embrace said pins by sliding the plate 0 into proper position.

If a more firm grip be required, it can be secured by means of a spring, 8. Such a spring, however,'is by no means essential in practicin our invention, for the plate cannot move in its ways unless the pin 0 is subjected to direct and positive pressure. There is no risk of any such pressure being accidentally imparted thereto, for it will be observed that the ends of said pin are flush with the respective planes of the upper and lower ends of the box-frame, that the diametrical size of the pin 0 is quite small, and that the opposite terminals of said pin entirely fill up the orifices into which they fall. Thus a blow or pressure upon either edge of the box-frame will not move the sliding plate unless intentionally exerted directly upon the flat end of the pin 0, and such pressure not extending beyond the diameter of a cross-section of said Having thus explained our invention and its operation, what we claim is 1. A finger-ring or analogous article of personal adornment having within a box-frame a reciprocally-sliding plate pierced with one or more key-hole slots, as herein shown and described, in combination with an interchangeable mounting provided with rearwardly-extending notched studs adapted to mesh with the slots of said sliding plate, substantially as described.

2. An article of jewelry'supplied with an open-box incasement for reception of an interchangeable mounting, said box having a rear panel, I), provided with one or more'orifices, b side frames, 1), and upper and lower end frames, b provided, respectively, with apertures b b, said box supplied upon one of its sides interiorly with a flange, 1, forming an annular groove, 2, and at its opposite side interiorly, near its upper end, with a permanently-attached short open-ended tube, 6 in combination with a sliding plate, 0, having lengthwise of one of its sides a pin,c, extend- ITO ing a short distance above and below the upper and lower edges of said plate, the terminals of said pinadapted to lie, respectively, within the orifices b b when the device is closed and movable upward and downward within the box B, whereby when said plate is pressed downwardly within said box the lower end of the pin 0 will pass outwardly through the orifice b, and the upper end thereof be guided within the tube 19 as and for the purpose intended, substantially as described.

3. An article of jewelry provided with a receptacle for insertion therein of an interchangeable mounting, A, having one or more rearwardly-extending notched pins, a, in combination with an arched plate, (J, provided with key-hole slots 0 adapted to intermesh with said notched pins and from which they will be released by the downward motion of said plate 0, as and for the purpose intended, substantially as described.

4. The combination of the sliding plate C, constructed as described, and its incasement B, with a pressure-spring, s, substantially as described.

5. An article of jewelry consisting of the following elements: an open incasement, B, having uprising from a back panel, I), opposite sides Z), upper and lower uprising ends b b said ends having aligning apertures b I), a short open-ended tube, 11 permanently attached to and within the upper part of one side of the incaseinent B, directly below the aperture If and opening therein, an annular groove, 2, at the opposite side within said in casement and extending the full length thereof, a sliding plate, 0, provided with key-hole
